4375 exoplanets identified! Researchers: Quantum communication could find extraterrestrial life
4375 exoplanets confirmed
In the 1940s, along with the appearance of a large number of UFOs over the United States, human exploration and research on UFOs and aliens began to unfold. Interestingly, however, humans did not even know whether there were exoplanets outside our solar system, and it can be said that the search for extraterrestrial civilizations was blind at the beginning.
When time entered the end of the 20th century, scientists finally confirmed the existence of exoplanets in the universe. Subsequently, in just 20 years, tens of thousands of exoplanet candidates have been found, of which 4375 have been confirmed, however, among so many planets, there has been no alien civilization.
How to find an alien civilization?
In recent years, because humans have been searching for extraterrestrial life for a long time on the road to nothing, so some researchers believe that the reason why humans do not have any clues may be that our own approach and direction of search is wrong.
So, humans need to expand our search while looking for extraterrestrial civilizations, as well as find new approaches. Researchers from the University of California, some time ago, came up with a new idea that humans might be able to find extraterrestrial civilizations through quantum communication technology.
What is quantum communication? In recent years, the research in the field of quantum mechanics has always been concerned, and quantum communication, is based on quantum mechanics, the use of quantum superposition state and quantum entanglement effect, so as to carry out a new type of information transfer, more bluntly, is a new high-tech communication, and more secure.
Compared to radio communication, quantum communication technology belongs to a more advanced communication technology, and for humans, is still in its infancy, which means that if there really is an alien civilization more advanced than the human civilization, then, they use the communication method, at least will be quantum communication level.
The staff of the Institute for Defense Analyses in Washington, D.C., believes that in cosmic China, aliens may be using microwave exciters for interstellar communication, simply put, the radio communication we use, in fact, has long been outdated, so there is a view that perhaps humans can locate alien civilizations by looking for the light pulses emitted by microwave exciters in the universe.
Researchers say that it is likely that in the universe, more advanced extraterrestrial civilizations have already made contact with each other, only that human civilization but because of its own scientific and technological level is not enough, resulting in has not been adjusted to their own frequency to the correct band, so that we can not receive the information of extraterrestrial civilizations, of course, may have received, but as a natural phenomenon in the universe and ignored.
Alien civilization may not want to be discovered by us
According to modern scientific research, about 6 billion years ago, there has been life in the galaxy, and at that time, in fact, the solar system has not yet appeared, from this point can also be seen, if the early galactic life is always continue to develop, then, their civilization is at least 2-3 billion years ahead of human civilization.
Researchers believe that we are a group of inferior intelligent creatures for alien civilizations, for these developed alien civilizations, they may not want to be found by us themselves, after all, humans will only communicate with humans, few people will really go willing to live with animals, and animals as friends.
Therefore, compared to quantum communication technology that can hide information, this may be one of the best ways for alien civilizations to communicate. If humans can detect entangled neutrino pairs in the future, this also means that we may have discovered an advanced alien civilization.
However, there is a question here, should humans really go actively searching for information about alien civilizations? Our listening for information about alien civilizations, once they find out, will not lead to disaster for mankind.
That said, many scientists believe that humans should not communicate with extraterrestrial civilizations, including Stephen Hawking, who has repeatedly said in public during his lifetime that it is not a wise move for humans to actively search for extraterrestrial civilizations.
You know, the solar system for alien civilizations, may be like the American continent for the European colonists in general, the difference in strength, once the alien civilization found the Earth's "eavesdropping", if they are angry to come to Earth, obviously, we will not have any good end.
Of course, there is a possibility that there is no alien civilization in the universe, according to the "big filter" theory, when the civilization has reached a certain stage of development, it will self-destruct, and then start a new civilization cycle, which may also be one of the reasons why we have not found an alien civilization, about which, what do you think?

NASA finds water ice on Mars, transforming the planet is on the agenda
Although in the same solar system in the habitable zone, however, the climate of Mars and Earth, is a world of difference. The thin atmosphere allows the surface of Mars to receive too much space radiation, and at the same time, Mars is very cold and dry. Researchers say that, compared to the driest places on Earth, Mars is about 1000 times drier than on Earth.

Met Office Issues Yellow Fog Warnings After Parts of UK Battered by Rain
After days of relentless rainfall sweeping across large parts of the United Kingdom, the Met Office has issued yellow fog warnings, cautioning residents and travelers to prepare for reduced visibility and hazardous conditions. The sudden shift from heavy rain to dense fog highlights the volatile nature of the UK’s winter weather and underscores the challenges it poses to transport, public safety, and daily life. From Heavy Rain to Thick Fog The recent spell of intense rain saturated the ground across England, Wales, and parts of Scotland, leaving rivers swollen and fields waterlogged. As calmer weather followed the downpours, a combination of high moisture levels, falling temperatures, and light winds created ideal conditions for fog formation. According to meteorologists, this type of fog—often called radiation fog—develops when moisture near the ground condenses overnight, forming thick, low-lying clouds that can linger well into the morning. The Met Office’s yellow warning signals that fog could significantly reduce visibility, in some areas dropping below 100 meters. While not the most severe level of weather alert, yellow warnings are designed to prompt awareness and caution, particularly for motorists, cyclists, and pedestrians who may be caught off guard during early morning commutes. Travel Disruptions and Safety Concerns Fog is one of the most dangerous weather conditions for road travel, as it can dramatically shorten reaction times and obscure hazards. Authorities have urged drivers to slow down, use fog lights appropriately, and maintain greater distances between vehicles. Motorways and rural roads alike are vulnerable, with sudden patches of thick fog appearing without much warning. Rail services may also experience delays, as drivers are required to reduce speeds when visibility drops. At airports, fog can disrupt flight schedules, causing delays or cancellations, particularly during peak morning hours. Aviation authorities closely monitor visibility thresholds, and even a short-lived fog bank can ripple through tightly scheduled operations. Emergency services have emphasized that pedestrians and cyclists should wear reflective clothing where possible, especially during early mornings and evenings. With darker winter days already limiting visibility, fog compounds the risks for vulnerable road users. Why Fog Follows Heavy Rain Meteorologists explain that fog warnings often follow periods of heavy rainfall. When rain saturates the ground, it leaves behind large amounts of surface moisture. If skies then clear and winds ease, the ground cools rapidly overnight, allowing moisture to condense into fog. This pattern is becoming increasingly familiar in the UK, where weather systems are growing more erratic. Climate scientists note that a warming atmosphere holds more moisture, increasing the likelihood of intense rainfall events followed by fog, frost, or sudden temperature drops. Regional Impact Across the UK The yellow fog warnings are not uniform across the country. Low-lying areas, river valleys, and rural regions are particularly susceptible. Parts of southern England, the Midlands, and eastern regions are among those most at risk, though localized fog could appear almost anywhere conditions align. In Scotland and northern England, lingering wet ground combined with colder overnight temperatures raises the possibility of fog forming alongside icy patches. This mix of hazards further complicates travel and increases the risk of accidents. What a Yellow Warning Really Means A yellow weather warning does not mean severe disruption is guaranteed, but it does indicate a heightened likelihood of impacts. The Met Office uses yellow alerts to encourage the public to stay informed and take sensible precautions. For fog, that means checking travel updates, allowing extra journey time, and staying alert to rapidly changing conditions. Weather experts stress that fog can be highly variable. One area may experience clear skies while another, just a few miles away, is blanketed in thick mist. This unpredictability is what makes fog particularly dangerous. Looking Ahead: More Changeable Weather Forecasts suggest that unsettled weather will continue in the coming days, with further spells of rain interspersed with calmer, colder nights—conditions that could lead to additional fog warnings. While no prolonged severe weather is currently expected, the pattern reflects the broader trend of increasingly changeable winters in the UK. For many residents, this serves as another reminder that winter weather is no longer defined by just cold or snow. Instead, a mix of heavy rain, flooding risks, fog, and sudden temperature shifts is becoming the new normal. Staying Prepared The Met Office advises the public to regularly check forecasts, especially before traveling, and to remain flexible with plans during periods of weather warnings. Simple measures—such as cleaning car windows, ensuring lights are functioning, and staying updated via official channels—can significantly reduce risk. As the UK continues to navigate this wet and fog-prone winter, awareness and preparation remain the best defenses. While the fog may lift by midday in many areas, its early impact serves as a timely reminder that even seemingly mild weather hazards can have serious consequences.

Wild Card Weekend Recap: What Happens Now?
I think I figured out why I love Wild Card Weekend so much. It's because it's the first playoff anything of the calendar year. The NFL season starts in the fall, and once upon a time, the champion was crowned either on or slightly before New Year's. The evolution of the NFL schedule has resulted in the playoffs starting just into the New Year, and currently, the final week of the season falls on the first weekend of the New Year, with Wild Card Weekend coming a week after that. So yes, chronologically, the NFL's Wild Card Weekend serves as the first playoff anything of the calendar year.
